Fuses: 0252.250M Application Field and Working Principle
Fuses can cover a wide range of application fields, from manufacture and automotive to motor control and power systems. The 0252.250M fuse is a fast-acting fuse that provides the protection of integral fuses in circuit designs for power semiconductor, motor control and power systems applications. This type of fuse has a quick response time, making it an ideal choice in mission-critical applications.
0252.250M Fast-Acting Fuse Working Principle
The 0252.250M fuse responds to overcurrent or short-circuit conditions with a current rating range of 0.125~6A. It is designed with a cavity for an integrated chip-on-board (COB) module with tin-plated copper terminals and fuse link. The fuse link consists of a bimetallic strip that melts when the current reaches the fusing current rating of the fuse, allowing a safe release of excessive current.
The COB module is filled with an inorganic powder mixture that produces a gas when heated. This gas helps to reduce any potential fire hazards by deflecting heat away from the fuse link and away from the device. The module also contains a pressure relief device that releases any pressure buildup inside the module.
The fuse is designed to provide instantaneous overcurrent protection by melting its link when the current in the circuit reaches its fusing current rating. This interrupts the circuit, preventing further damage and ensuring reliability in the system. The break-time of the 0252.250M fuse is less than 10 milliseconds, providing fast response protection.
Applications
The 0252.250M fuse is a wide-ranging protection device, suitable for use in power semiconductor, motor control and power systems. It is rated DT for through-hole mounting, and features SMD technology for surface-mount applications. Some of its key applications include:
